Actually, files whose names start with "." in the root directory of the filesystem tree will stay then.

* is interpreted by the shell though. I guess what dannym meant was that it would leave out "hidden" files, or files starting with a dot.

I'll start with something rather simple to get this going.
Code:echo `head -2 < /proc/meminfo | awk '{print $2}' | sort -n` | awk '{printf("You have $1 kb of $2 kb free memory")}'
(Of course, the $n must be replaced with %i, and listed after the output string, as mentioned by fnordianslip above.)

Search for <phrase> in all files below <path> (Recursive):
I.e. search for files containing the word N900 in the MyDocs folder:
EDIT - Adding -i would do the same, only incase sensitive.

Code:
grep -R <phrase> /<path>
Code:
grep -R N900 /home/user/MyDocs

I wanted to write cat /dev/urandom > /dev/dsp ,but it doesn't work on n900 
on ubuntu, it sends random symbol to speakers and so you hear the "white noise"

(And forgot about .* hidden files.)Btw *.* won't catch files or directories without 'in middle' dot.
